Adult Sheldon: Presenting... "Sheldon Cooper's Top Five Sources of News From My Childhood". Number five: Star Trek Fan Club Magazine.
Sheldon: Mom, DeForest Kelley's favorite episode is "The Empath."
Mary: Good to know.
Adult Sheldon: Number four: the Weather Cube from RadioShack.
Man: [from device] The humidity is 90% with a dew point of 79.5 degrees.
Sheldon: Mom! The dew point is 79.5 degrees.
Mary: [o.s.] Okay.
Adult Sheldon: Number three: The MacNeil/Lehrer NewsHour. Such a great theme song.
Sheldon: [hums] Buh-buh-bum.
Adult Sheldon: Number two: Meemaw after a few beers.
Meemaw: It took a while, but we finally picked a new name for my bowling team: The Ball Busters.
Sheldon: Hey, Mom. Guess what Meemaw named her bowling team? The Ball...
Adult Sheldon: And the number one source of news from my childhood: the bulletin board at the train store. News about trains in a store full of trains. Yummy.
Sheldon: How did this not make The MacNeil/Lehrer NewsHour?

Mary: [eating pop corn] Get him, Dalton. Get him.
Georgie: Mary Cooper, what are you doing?
Mary: Nothing.
Georgie: Why are you watching Road House?
Mary: Why aren't you at work?
Georgie: I asked you first, and my question is way more interesting.
Mary: It was just on. I don't even know what that is.
Georgie: Then how'd you know his name's Dalton?
Mary: I don't have to explain myself to you.
Georgie: This is a pretty dirty movie.
Mary: How do you know? It is rated R.
Georgie: For violence, language and sexual content. You should be ashamed of yourself.

Meemaw: Alls I'm saying is people aren't always in the mood.
Sheldon: Well, they should be. I'm happy to learn any fact at any time.
Meemaw: Is that so?
Sheldon: Yes.
Meemaw: Grab my knitting bag.
Sheldon: I don't recommend driving while knitting. Your reflexes aren't what they used to be.
Meemaw: Just look in the bag! Did you know that there are three different kinds of yarn?
Sheldon: I didn't.
Meemaw: You got your animal, like wool. Your plant, like cotton. And your synthetic, like acrylic.
Sheldon: Interesting.
Meemaw: You think so? I'm glad to hear that. Because each one of them has plusses and minuses, and you're about to hear them all in mind-numbing detail.

Georgie: So how many times have you seen Road House?
Mary: Sorry, can't hear you.
Georgie: More or less than five? 'Cause that'show many times I've seen it.
Mary: That's how many years you're gonna be grounded if you don't drop it right now.
Georgie: Does Dad know you like this movie?
Mary: [vacuum stops] No, and it is gonna stay that way.
Georgie: Why?
Mary: Because it is not something I should be watching.
Georgie: Then why are you watching it?
Mary: It is a guilty pleasure, so will you drop it now?
Georgie: Relax. I ain't gonna tell nobody.
Mary: Thank you.
Georgie: I think it's awesome you like it.
Mary: It is pretty cool how Dalton doesn't drive his Mercedes to the bar 'cause he knows they're gonna trash it.
Georgie: Dalton's no dummy.
Mary: No, sir.

Georgie: How awesome was it when he fights those four guys at once?
Mary: They were asking for it. Dalton doesn't fight unless he has to.
Georgie: True, 'cause when the doctor says, "How many of these fights you win?" he says...
Both: Nobody ever wins in a fight. [both laugh]
Mary: Mm, and I like how smart he is. But doesn't feel like he has to show it off.
Georgie: No kidding. Maybe Sheldon should watch it.
Mary: Hey, what was Dalton's third rule of being a good bouncer?
Georgie: Be nice.
Mary: That's right.

Sheldon: The train museum's looking for a docent.
Mary: What's a docent?
Sheldon: It's a person in a museum who gives information on the exhibits.
Mary: Do you think they'd let someone your age do that?
Sheldon: Why not? I have a high school diploma.
Mary: True.
Sheldon: I know more about trains than anybody.
Mary: True.
Sheldon: And I have the unique ability to wear people down until I get my way.
Mary: So true.

Sheldon: [on the phone] Hello. I understand you're looking for a docent. I'm 11 years old, but you should know I have a high school diploma and I know more about trains than anybody. You still sound on the fence.
Adult Sheldon: It was time to break out my unique ability.
Sheldon: Let me tell you about every model train I own and what each of them means to me. The first locomotive I ever received...
Adult Sheldon: Wouldn't you know it, 47 short minutes later, I got the job.

George: What do you got going on today?
Mary: Ooh, laundry, grocery shopping, vacuuming. I might go nuts and dust the picture frames.
George: Well, nice. Everybody's doing something they love.

Mary: Sheldon, you sure about this?
Sheldon: Yes, leave the crusts on. I'm a docent now.

Lawrence: I like your conductor's uniform.
Sheldon: You know what they say. Dress for the job you want. Do I get an "ask me" button, too?
Lawrence: Well, thank you for asking, and yes, you do. I'll be right back. [exits]
Sheldon: Do you see that bell? That's from Texas and New Orleans locomotive number 701. I'd tell you more, but you haven't contributed the suggested donation.
[Sheldon stares at Meemaw until she puts some money in the donation box]
Sheldon: Number 701 was built in 1930 by the Baldwin Locomotive Works. It was a superheated 44 class GS-1 with ...
Meemaw: I want my money back.
Lawrence: Here you go.
Sheldon: Thank you. [to Meemaw] I know you're supposed to pick me up at 4:00, but I may live here now.
Meemaw: Send me a Christmas card.

Lawrence: Just let me know if you have any questions.
Sheldon: This is a very nice builder's plate. How can you be sure it's not a replica?
Lawrence: Now, that is a great question.
Sheldon: Thank you. I also know the answer. Do you?
Lawrence: Well, there's, uh, rust and soot on the back of it from when it was mounted to the engine's smokebox.
Sheldon: Very good. Ah, the 1947 Santa Fe diesel. I've always loved that paint scheme. I wonder if they had a name for it.
Lawrence: Cat's Whiskers.
Sheldon: Correct.
Lawrence: Ha! Two for two.
Sheldon: Did you know that the word "train" comes from the French verb traîner, which means to draw or drag?
Lawrence: [chuckles] Well, I just learned something.
Sheldon: Well, if you enjoy learning things, then you and I are on the "fast track" to friendship. Speaking of fast tracks, the Japanese bullet train, or Shinkansen...

Sheldon: It's almost opening time. Can I flip the sign?
Lawrence: Have at it.
Sheldon: [pulls out stopwatch] Five, four, three, two, one. [flips sign] We're officially open for business. [Sheldon peeks outside to see nobody waiting for the store] Anticlimactic.

George: Nothing to be embarrassed about. It's perfectly natural. Perfectly normal.
Missy: Dad, I know.
George: I'm telling myself. Uh... How much money you need?
Missy: I'm not going in there. You are.
George: Why can't you go? It's embarrassing.
Missy: You just said it wasn't embarrassing.
George: Well, it is and I lied.

Norman: Excuse me.
Sheldon: Hello. Welcome to the Lone Star Train Museum. I'm Docent Sheldon Cooper. If you have any questions... [taps "Ask Me" badge]
Norman: You know where the bathroom is?
Sheldon: Indeed I do. You'll want to chug along past our authentic Southern Pacific Sunset limited whistle, then keep going past our conductor's uniform, which was worn on the Texas and Pacific Railway. Then you'll come upon...
Norman: Son, I have to take a leak.
Sheldon: It's in the back.
Norman: Thank you.
Sheldon: And our toilets flush, unlike the ones on trains before 1889.

Sheldon: This is a genuine locomotive bell from Texas and New Orleans number 701. Now there's a proper technique to make the purest sound. Most people don't know how to do that. But you're in luck, because I do. [bell ringing]
